Title: Original reader
Inventor: TAKEUCHI SHIGEKI
IPC: H04N1/04
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To prevent the reader from being affected of vibration caused at transportation even when a platen glass is kept closing by providing a means that receives entry of a carriage moving instruction and a means that stops a carriage when the carriage is moved at a prescribed position to the reader. SOLUTION: In the case of setting the transportation mode, a motor is driven to move a mirror carriage 28 to the home position, that is, a home sensor position (S). A motor step number from the home sensor position (S) to a fixed position (F) is set to a prescribed register in a RAM. The motor is driven to start movement of the mirror carriage 28 in a direction of the fixed position (F). The motor step number is monitored till the mirror carriage 28 is moved by the set step number and when the carriage 28 is fed by the set step number, it is discriminated that the mirror carriage 28 reaches the fixed position (F) and the mirror carriage 28 is stopped. Finally a transportation mode state variable is set to inhibit the movement of the mirror carriage 28.
